IMPROVEMENT IN MACHINES FQR CLAMPING AND SQUARENG SASHES Specificationforming part of Letters Patent No. HEZ'QLEQS E, dated May S, 1877;application filed November 4, 1876.

To all whom it may concom:

Be it known that I, Josnrn Course, of Reynoldsville, in the county ofJett'erson and State of Pennsylvania, have invented certain new anduseful Improvements in Machines for Clamping and Squaring Sashes; and Ido hereby declare the following to be ai'ull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification.

My invention relates to an improvement in machines for clamping andsquaring sashes and it consists in the peculiar construction andarrangement of clamping devices with the other operative parts of themachine, as will be hereinafter more fully specified.

The accompanying drawings represent my invention.

a represents a frame, of any desired form or construction, and which hassecured upon its top, at right angles to each other, the two bars 0,which form the surfaces against which the sashes are forced by the twoslides. Extending parallel across the top of this frame are the twobeams d, which form not only the rest upon which the sash is placed, butthe guides between which the clamping-slide 0 moves. This slide e.isconnected by the two screw-rods g to a quarter-wheel, h, which ispivoted in the frame, and which wheel is connected at its oppositecorner by the rods i with the treadle j. Extending at right angles tothe two beams 61 are two shorter beams, l,

between and on which inovesa second clamp,

n, which is attached to a second quarterwheel, 0, placed at right anglesto the first, by a screw-rod, 1", which wheel is also connected to thetreadle by a rod, 8. By means of tin screw-rods the slides can beadjusted bacli and forth to suit different sizes of sashes.

By the employment of these quarter or seg' mental wheels, acted directlyupon by the treadle-rods i and s, the wheel It can be brought up muchnearer to the beam 0, and a much smaller sash clamped, than could bedone in case sliding clamping-bars were employed, as heretofore. Theclamping mechanism is also greatly simplified, and less liable to getout of order.

by hearing down on the treadle both slides advance at right angles toeach other, and, pressing the sash against the two bars 0, clamp it inposition, and square it at the same time. Ehe treadle is held in anydesired position by the ratchet t.

I am aware that two slides moving at right angles to each other, forclamping and squaring sashes, are not new, and do not broadlyclaiinsuch, the same being shown in the patent to J. H. Hume, June la",I870.

Having thus described my invention, I claim In a machine in which thesash is both squared and clamped at the same t me, the construction andarrangement, with thebeains 046 l, oi" the clamping devices, consistingof slides c a, rods 7' g, and segmental wheels operated directly by thetreadle rods, as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this30th day of October, 1876.

JOSE PH COLLINS.
